day trading is a tense process. One has to be mindless in order not to effect his/her sleep. Sure when $$$$ is small enough not to be cared for, then why get involved in the first place. Small money just doesn't get big returns. Anyone who can make a living with 25K, the minimum requred by the rule for day traders, has to achieve a return of 100% year in year out. There might be some chest pounding dudes who make the performance claim. I seriously doubt they can make the claim of not losing any sleep. For the majority, to day trade is to say bye bye to good night sleep no mater one makes $$ or loses it.
